MENLO PARK, Calif., Dec. 23 /PRNewswire/ -- ShoutOUT TXT, the first dedicated full-featured text messaging application for iPhone with voice dictation is now available for download in the App Store.

Developed by Promptu Systems Corporation, ShoutOUT TXT is a complete SMS texting app that lets users type or speak messages in fluent natural speech. Transcribed spoken messages are returned in seconds. Using Promptu SmartWord(TM) editing, users tap a word to see and select from likely alternatives before sending their messages on to the intended recipient.

ShoutOUT TXT standard features include:

Inbox and outbox

Message exchanges threaded by recipient

Send to multiple recipients

Notification of incoming messages

Thumbnail images for contacts

One-touch navigation to all recent incoming and outgoing messages

"There's no faster, easier way to create and send text messages on your iPhone than with ShoutOUT TXT," said Giuseppe Staffaroni, Promptu's CEO. "ShoutOUT TXT allows you to send and receive SMS messages at a cost far lower than the standard rates charged by operators."

All text messages created using only the keyboard are always free. Users pay only pennies for spoken and transcribed messages.

"Speech is the most natural and intuitive form of human expression - so write with your voice," said Staffaroni. "ShoutOUT TXT lets you get your message across much more easily and completely, and our large font option makes ShoutOUT TXT a great multitasking tool."

ShoutOUT TXT voice recognition is server-based, and 100 percent automated. All message transcriptions that appear on users' handsets are created without any human intervention whatsoever, so privacy is guaranteed.

ShoutOUT TXT is built on state-of-the-art voice recognition technology and optimized for North American English. Accuracy varies from person to person and will improve over time with use.
